Subject: [PATCH v2 02/19] powerpc/powermac: Mark variable x as unused

From: Mathieu Malaterre <[email-masked]>
Date: Wed, 28 Mar 2018 21:30:28 +0200

Since the value of x is never intended to be read, remove it. Fix warning
treated as error with W=1:

  arch/powerpc/platforms/powermac/udbg_scc.c:76:9: error: variable ‘x’ set but not used [-Werror=unused-but-set-variable]
